从一个MySQL表中获取所有记录并将其插入到另一个MySQL表中？
为此，您可以使用CREATETABLEASSELECT语句的概念。让我们首先创建一个表-
mysql> create table DemoTable1518 -> ( -> EmployeeId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> EmployeeName varchar(20) -> )AUTO_INCREMENT=101;
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1518(EmployeeName) values('John Doe');
mysql> insert into DemoTable1518(EmployeeName) values('John Smith');
mysql> insert into DemoTable1518(EmployeeName) values('David Miller');使用select语句显示表中的所有记录-
mysql> select * from DemoTable1518;
这将产生以下输出-
+------------+--------------+ | EmployeeId | EmployeeName | +------------+--------------+ | 101 | John Doe | | 102 | John Smith | | 103 | David Miller | +------------+--------------+ 3 rows in set (0.00 sec)
以下是从一个MySQL表中获取所有记录并将其插入到另一个MySQL中的查询-
mysql> create table DemoTable1519 as select * from DemoTable1518; Records: 3 Duplicates: 0 Warnings: 0
使用select语句显示表中的所有记录-
mysql> select * from DemoTable1519;
这将产生以下输出-
+------------+--------------+ | EmployeeId | EmployeeName | +------------+--------------+ | 101 | John Doe | | 102 | John Smith | | 103 | David Miller | +------------+--------------+ 3 rows in set (0.00 sec)
